From d671d5e51400aab03c713a16ce3545aa81ad7b1c Mon Sep 17 00:00:00 2001 From: Al Viro Date: Mon, 6 Jun 2005 13:36:04 -0700 Subject: [PATCH] [PATCH] namei fixes (8/19) In open_namei() we never use path.mnt or path.dentry after exit: or ok:. Assignment of path.dentry in case of LAST_BIND is dead code and only obfuscates already convoluted function; assignment of path.mnt after __do_follow_link() can be moved down to the place where we set path.dentry. Obviously equivalent transformations, just to clean the air a bit in that region.
